+### Frequently Asked Questions
+
+<AccordionGroup>
+  <Accordion title="Why can't I edit my response?">
+    Rallly uses cookies in your browser to recognize you as the creator of a
+    response. If your cookies have been deleted or you are using a different
+    device/browser, you may no longer be recognized as the user who created the response.
+
+In this case you should ask the administrator of the poll to either delete your
+response so that you can create a new one or to edit your response for you.
+
+  </Accordion>
+  <Accordion title="How can I avoid losing access to my own response?">
+  If you enter your email address when you submit your response, you will
+  receive a confirmation email with a link that allows you to edit your response from
+  anywhere.
